CENTER-SLOT STEEL FURNITURE,

Specification of Letters Patent. Patented J i 1, 192() Application filed May 9, 1919. Serial No. 295,964. 1

To all whom it may concern: 7

Be it known that 1, JOHN A. RUTHERFORD, a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Center-Slot Steel Furniture, of which the following is a specification.

The invention relates to printers furniture and has for its object to provide metal furniture which is labor saving and insures a perfect and solid square lock-up of printers form in any size whatever, either large or small and which will obviate any springing or bending and insure absolute register of press forms which is essential for the make up of various nmlti-colored register work. l\loreover, the present invention provides metal furniture which will guard against the possibility of the type matter,

quads, leads, slugs, and other material from Working up in any kind of form to be used.

in printing.

In accordance with the present invention the steel furniture is provided with a center slot and end mortises and may be made up in any desired lengths in multiples of half inches so that the parts may be rapidly and departing from the nature of the invention as claimed hereinafter.

In the accompanying drawing, Figure 1 is a top view of a form made up of different lengths of center slot and end mortises, steel furniture embodying the ini 'mg have reference to what may be considvention and Fig. 2 is a perspectlve view of a single length of such furniture.

Fig. 1 respresents a printing form or lookup embodying steel furniture having center slot and end mortises, the same being arranged within a chase 1 of ordinary construction and made secure therein by quoins 2 in a manner well understood. The forms are comprised between ordinary furniture-3 which is disposed between the members of the chase and the outer lengths of the center slot steel furniture.

The numeral 4: designates lengths of steel furniture embodying the invention, each of such lengths being provided with acenter slot 5 andend mortises 6. The furniture 4 which is preferably of steel may be made in any desired lengths preferably in multiples of half inches so that they may be assembled rapidly and accurately, the center slot 5 al ways falling in the center of any half inch combination to be made up. The end mor tises correspond in depth to the depth of the center slot 5, thereby admitting of corresponding lengths fitting accurately. When the furnlture is arranged with two or more lengths in line itis disposed with the mortise ends abutting,as indicated most clearly in Fig. 1. The space formed by the mortises at the ends of adjacent sections is adapted to receive the projecting ends of sectionsdisposed side by side with their slots facing outwardly in opposite directions, as shown most clearly in Fig. 1 The lengths of the furniture being uniform or in multiple insures forms of uniform dimensions so that the matter set up will register and insure neat and accurate work in multi-color printing. It will be understood that furniture for printers use constructed in accordance with the invention enables a form to be made upwith a minimum number of pieces and when the form is made up the quoins may be arranged in line with the furniture separating the forms, thereby preventing any possible bending or distorting of the furniture which usually tends to throwthe 7 forms out of line and which is the source of considerable trouble in work requiring'the forms to register. I g The .foregolng description and the drawercd the preferred, or approved form o'fmy invention. It is to be understood that I may make such changes in construction and arrangement and combination, of-parts, mate- Havingthus fully described my invention, What I claim as new and desire to secure by Letters Patent.is: V 7

Printers furniture comprising lengths of steel, each length having a center slotiand end mortises of uniform depth adapted to form a corner thereby providing a fed- 16 tangular frame, said mortises fitting the said center slots.

In testimony whereof I afiix my signature in presence of two Witnesses.
